When any lever is balanced the clockwise torque must what?
When a lever is balanced, the clockwise torque must equal the counterclockwise torque. This means that the product of the force applied and the distance from the pivot point must be the same on both sides of the lever.
What kind of simple machine is a seasaw?
A seesaw is a lever balanced on a fulcrum.
What is a lever balance?
A lever balance is a simple machine used to measure weights by comparing an unknown weight to a known weight. It consists of a bar that pivots on a fulcrum, with the two sides of the bar holding the weights. When the lever is balanced, the weights on each side are equal.
Why it is necessary to being the lower arm of lever in horizontal position after applying the load?
Keeping the lower arm of the lever in a horizontal position after applying the load ensures that the lever is balanced, allowing for efficient and effective use of the lever's mechanical advantage to lift the load. If the lower arm is not horizontal, the lever may become unbalanced, making it difficult to control the load and potentially causing accidents.
What simple machine has a continuous lever with equal arms?
A seesaw is a simple machine that has a continuous lever with equal arms. When one end of the seesaw is pushed down, the other end goes up, demonstrating the principle of a lever with balanced arms.

How is a lever balance used to measure mass?
A lever balance is used to measure mass by comparing the weight of an object on one side of the lever to a set of known weights on the other side. The lever is adjusted until the two sides are balanced, indicating that the weights are equal and providing the measure of the object's mass.
Is a balanced scale a first-class lever?
Yes because the fulcrum is in the middle the effort is on one side and the load is on the other side
What class is the teeter-totter?
The teeter-totter is a simple machine classified as a lever, specifically a type of lever called a seesaw. Being a lever, it operates by a pivot point (fulcrum) with two balanced forces acting on either side.
When resistance force is increased on a lever what happens to the effort force?
When the resistance force is increased on a lever, the effort force required to lift it also increases. This means more force is needed to overcome the resistance and achieve a balanced system.
Why are the other 2 types of structures not weakened by lever action?
Other structures are not weakened by lever action because they are designed to resist the forces produced by the lever action. For example, arches and domes are capable of distributing loads evenly, resulting in a balanced force distribution that minimizes the impact of lever action. Additionally, truss structures can handle the loads imposed by lever action by efficiently transferring the forces through their network of interconnected members.
What is the law of lever?
The law of the lever states that the effort multiplied by the effort arm equals the load multiplied by the load arm in a lever system, allowing for the calculation of mechanical advantage and equilibrium. This principle governs how force is applied and distributed in a lever system.
Where can a first class lever be found in the body?
A first-class lever can be found in the body at the atlanto-occipital joint, where the head is balanced on top of the neck. The effort (muscle force) is applied at the back of the head when nodding forward, the fulcrum is at the joint itself, and the resistance is provided by the weight of the head.
